Two-dimensional Na–Cl crystals of unconventional stoichiometries on graphene surface from dilute solution at ambient conditionsTwo-dimensional Na–Cl crystals of unconventional stoichiometries on graphene surface from dilute solution at ambient conditions, Published online: 07 May 2018; doi:10.1038/s41557-018-0061-4The common form of salt has a 1:1 ratio of Na+ and Cl−; however, species that deviate from this can be found under extreme conditions, such as high pressure. Now, as a result of cation–π interactions that promote ion–surface adsorption, Na2Cl and Na3Cl have been observed as two-dimensional crystals on graphene at ambient conditions.
